1. Field of the Invention
The present invention relates to an air valve connecting head or device, and more particularly to an air valve connecting device including a simplified structure for easily connecting to different inflation valves of U.S. type and French type valves and for being easily manufactured with a decreased manufacturing cost.
2. Description of the Prior Art

The handle 40 includes a cam member 43 formed or provided on the one end 42 thereof. A cylindrical grasping member or barrel 50 is further provided and engaged into the chamber 11 of the housing 10 and engaged onto the mouth 20, and includes a bore 51 formed therein, and includes a space 52 formed in the lower portion thereof and having an inner diameter greater than that of the bore 51 of the barrel 50 for receiving or engaging with the stud 22 of the mouth 20 and for stably anchoring the barrel 50 to the mouth 20, and includes an enlarged or inclined or cone or frustum-shaped space 53 formed in the upper portion thereof.
An actuating member or actuator 60 is slidably engaged in the other one end or the upper portion 15 of the housing 10, and includes a peripheral groove 61 formed in the outer peripheral portion thereof for receiving or engaging with a sealing ring 62 and for engaging with the inner peripheral portion of the housing 10 and for making a water tight or air tight seal between the actuator 60 and the housing 10, and includes a shank 63 extended downwardly therefrom for contacting or engaging with the barrel 50, and having an outer diameter smaller than that of the actuator 60 for forming an outer peripheral shoulder 64 between the shank 63 and the actuator 60, and for allowing the pressurized air from the air pump (not shown) to flow through the passage 19 of the housing 10 and to flow into the chamber 11 of the housing 10, and includes a chamber 65 formed in the shank 63 or the actuator 60, and includes a stem 66 extended downwardly into the chamber 65 of the shank 63 or the actuator 60.
The actuator 60 includes one or more slits 67 longitudinally formed in the outer peripheral portion of the shank 63 for forming two or more spring blades 68, and includes an inclined or cone or frustum-shaped segment 69 formed in the lower portion of the shank 63 for engaging with the cone or frustum-shaped space 53 of the barrel 50 and for selectively forcing the spring blades 68 toward each other or toward the center portion of the actuator 60, and includes a projection or pawl 70 extended radially and inwardly from each of the cone or frustum-shaped segments 69 or of the spring blades 68, and the pawls 70 may be forced to move toward each other (FIGS. 4, 5) when the actuator 60 is moved downwardly toward the barrel 50 and/or the mouth 20. A spring biasing means or member 71 is engaged between the barrel 50 and the peripheral shoulder 64 of the actuator 60 for biasing or forcing the actuator 60 away from the barrel 50.
A valve pressing member or tube 72 is slidably engaged in the chamber 65 of the shank 63 or the actuator 60 for selectively engaging with the French type valve 80 (FIG. 4), and is slidable or extendible into the compartment 24 of the mouth 20 for selectively engaging with the U.S. type valve 88 (FIG. 5), and includes a cavity 73 formed therein for receiving or engaging with the stem 66 of the actuator 60 and for guiding the tube 72 to slide relative to the actuator 60, and includes a peripheral flange 74 extended laterally and outwardly therefrom for engaging with another spring biasing means or member 75 which is engaged with the actuator 60 for selectively biasing or forcing the tube 72 away from the stem 66 of the actuator 60 and for biasing or forcing the tube 72 toward and to engage with the inflation valves 80, 88 (FIGS. 4, 5), and includes a peripheral recess 76 formed in the outer peripheral portion thereof and formed or defined by the peripheral flange 74 and another peripheral rib 77 of the tube 72.
In operation, as shown in FIG. 5, a U.S. type valve 88 may be engaged through the opening 32 of the cover 30 and may be engaged into the compartment 24 of the mouth 20, and the tube 72 may be forced to engage with the U.S. type valve 88 by the spring member 75.

The actuator 60 may also be forced to engage with the barrel 50 and the mouth 20 and to force the mouth 20 to solidly engage with and grasp the U.S. type valve 88.
Alternatively, as shown in FIG. 4, the French type valve 80 may be engaged through the opening 32 of the cover 30 and may be engaged into the compartment 24 of the mouth 20 and may also be engaged into the chamber 65 of the shank 63 or the actuator 60, and may force the tube 72 to engage with the spring member 75. The cam member 43 may then be forced to engage with the actuator 60 by rotating the actuating handle 40 relative to the actuator 60 and the housing 10 to the perpendicular working position, at this moment, the actuator 60 may be forced to move downwardly toward the barrel 50 and/or the mouth 20, and the pawls 70 of the spring blades 68 may be forced to move toward each other and may be forced to engage with the French type valve 80 in order to solidly retain the French type valve 80 to the actuator 60 and the housing 10. The actuator 60 may also be forced to engage with the barrel 50 and the mouth 20 and to force the mouth 20 to solidly engage with and grasp the French type valve 80.
Accordingly, the air valve connecting device in accordance with the present invention includes a simplified structure for easily connecting to different inflation valves of U.S. type and French type valves and for being easily manufactured with a decreased manufacturing cost.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
